Index based file search

Hi,

Is there an index based file search utility availble for linux.

What is the fastest file search utility available for linux

Thanks a lot,
CHamal.

To my knowledge "whereis" is probably the quikest... (terminal command)

Thanks UgoDeschamps,

Does that command(whereis) uses file indexing. If it does do I have to update the index regularly. Can I search inside sub folders with that command.

Thanks a lot,
Chamal.
